As some people already let me know, you can encounter a plasmatic crash right at startup which prevents the desktop from loading.A workaround is to# mv /opt/kde4/lib/libkholidays.so.4.6.0 /opt/kde4/lib/libkholidays.so.4.6.0.bakbut you'll lose the clock/calendar applet :-(Another inconvenience is a number of warning popups shown when connecting to secured websites in Konqueror. They also start a knotify process that gives out annoying bell and eats a lot of CPU.Last bad news is the loss of KDEaccessibility. Upstream has introduced hard dependency on speechd, so we can't compile until someone creates a spec for it.
